West Cornwall seems to be overlooked. It is a real toughie as well.
Of the courses I have designed or co-designed only once have I started with a '3'. Players Club Stranahan course.
Being commercial it was important I had something that could be played in 8 minutes. At 105 yards it is played to a big island. Plenty do go in the water, but it plays perfectly for a 4 ball in 8 minutes and we have no real issues with tee times backing up based on 45 seconds per tee shot, 60 seconds the walk. The 4 minutes left is plenty of time for the putting or extra tee shots!!! Our 200 yard 10th hole which plays 175 for standard play takes an average of 10'30" to play, naturally if everyone hits the green it plays to 8 minutes, but more miss this green and the bunker shots, recoveries from grass hollows can add up so some can take 13 minutes.
My thoughts would be if you can have a shortie gathering the ball rather than repelling, is best practice if it is commercial. If it not then it is a great natural spacer and flow regulator and a standard short hole is fine. I don't know this for a fact by would imagine something like the 1st at Meyrick Park would operate as a call through hole.
